Telecommunication Markets. Drivers and Impediments

The last decade has seen a large wave of deregulation in telecommunications markets. Liberalization is also taking place in other network industries which were originally organized as monopolies, such as railway, electric power and natural gas. These industries share a common characteristic. An incumbent, which often is a formerly state owned company, is the sole proprietary of a network. When the industry is opened to competition, entrants buy access to the network infrastructure of the incumbent and are therefore enabled to provide the same or a somewhat differentiated product in the market. Hence it is believed that competition in the market will increase, which should lower prices, and in turn, increase consumer surplus.

Intelligent Agents for Telecommunication Applications

The telecommunication market is changing very rapidly. On the one hand, the basic technologies for telecommunication in general are developing very fast. On the other hand, the liberalisation of the telecommunication market has urged the existing network operators to open their networks to new suppliers. A result is the network for everyone. The offered network services will be crucial with respect to the competition in the future market. Therefore, the telecommunication market will have to use existing networks efficiently and to control them. Also, the conception of innovative services and the provisioning of these new services will be an important task. These future services will have to meet a number of requirements as described in the introduction of this book.

History and Theory in Anthropology

Anthropology is a discipline very conscious of its history, and Alan Barnard has written a clear, balanced, and judicious textbook that surveys the historical contexts of the great debates in the discipline, tracing the genealogies of theories and schools of thought and considering the problems involved in assessing these theories. The book covers the precursors of anthropology;evolutionism in all its guises; diVusionism and culture area theories, functionalism and structuralfunctionalism;action-centred theories;processual and Marxist perspectives;the many faces of relativism, structuralism and post-structuralism; and recent interpretive and postmodernist viewpoints.

Telecommunication Circuits and Technology

Communication systems consist of an input device, transmitter, transmission medium, receiver and output device, as shown in Fig. 1.1. The input device may be a computer, sensor or oscillator, depending on the application of the system, while the output device could be a speaker or computer. Irrespective of whether a data communications or telecommunications system is used, these elements are necessary.

Security of Digital Enhanced Cordless Telecommunication (DECT) devices for residential use

The Digital Enhanced Cordless Telecommunication (DECT) standard provides voice, data and networking applications; currently there are about 31.5 million DECT devices only in Germany. Attacks and new analysis methods were published on www.dedected.org in 2008. In this thesis DECT devices of different manufacturers were analysed with the help of the named methods; due to that it was firstly possible to deliver insight into the current security status of DECT devices for residential use. The amount of implemented security mechanisms as recommended by the European Telecommunication Standard Institute (ETSI) is revealed through these examinations. Finally this thesis arrives to the conclusion that none of the tested devices provides a global protection of authenticity and privacy.
